At most only 1% of our dietary intake will be absorbed by the body, and that relies on digestive efficiency and the presence of a chemical called intrinsic factor. Tiredness, stress, ill-health, poor or limited diet will all reduce this absorption further. As it is predominantly found in animal products, B12 supplements are recommended for those following vegetarian and vegan diets and Pernicious Anaemia sufferers.
